Longhorn Moths

A male longhorn moth, probably Adela reaumurella (Lepidoptera: Adelidae). One of several that I saw on my walk round the lakes on on Saturday.  Photo taken in Whiteknights Park, Reading University grounds, Reading, UK, on 2011-04-09.

On the following afternoon I saw several several swarms of these moths on a walk to Mapledurham.  The swarms seemed to consist of only males, all vigorously twirling their long antennae.  I did see one female (much shorter antennae and a greenish-gold sheen rather than a silvery black - see here) but it was by itself down in the undergrowth, well away from the swarms.  Photo taken in Chazey Wood, near Caversham, UK, on 2011-04-10.
